UNITED "ST T 1 IATENTYOFFICE SPRING WHEEL FOR ROAD vEHIoLEs.

Application filed December 11, 1925, Serial No..74,810, and in Union ofSouth Africa September 25, 1925.

This invention has reference to elastic, resillent or spring wheelsapplicable for use with all kinds of road vehicles and especially Zmotor cars and similar vehicles.

The ObJBCt of the invention Is to construct a wheel of the naturereferred to which can be used in place of pneumatic-tyred wheels orother resilient rubber-tyred and similar wheels. By the use of wheelsconstructed according to the invention, the trouble that ensues withpneumatic tyres, owing to their becoming deflated, is obviated.

My improved elastic or resilient wheel is of simple design, inexpensiveto construct and eflicient in use. 7 1

The invention will be described in detail in connection with theaccompanying drawings, wherein I illustrate a practical embodiment ofthe same. In. the drawings,

Fig. 1 is a half-sectional front elevation of the improved wheel, and Ia Fig. 2 is a half-sectional side elevation of the same.

The wheel structure is shown including the hub portion or centre piece 1of any suitable design or construction to adapt the 1 wheel to the axleof any'particular vehicle.

The hub 1 is shown constructed integral with a disc portion 2 fashionedat or near one end of said hub 1; 3 being a similar disc detachablysecured at or near the other end of the hub portion l by means of a keyor its equivalent 4 and additionally retained in position by the nut oraxle cap 5.

Around the outer portions of the discs 2, 3, therev is arranged a rim ortyre-carrying portion 6, which is fashioned internally with two inwardlydirected parallel annular flanges 7 8, which, as shown in the sectionalhalf of Fig. 1, project between, and are adapted to work in the spaceor' guideway provided by and between the outer parallel portions of thediscs 2, 3.

9 represents a rubber or other suitable tyre appropriately securedaround the rim portion 6. v v

The rim portion 6 and the flanges 7, 8, which are shown constructedintegral therewith, are resiliently connected to the discs 2, 3, andthrough the latter to the hub 1, by means of a suitable number of C orcoiled metal springs 10, one end of each of v the flanges '7,

the flanges 7, 8, and 3. The means shown of the springs 10 to .8,consists of cross pieces 11, 12, formed on the flanges and extendingbetween them, and providing between them spaces or openings 13 in whichthe endsof the springs 10 are secured by means of the set screws 14. Theend of each spring may be further secured, if desired, by means of a pin15 placed in a hole in the end of the spring and engaging withthe'crosspieces ll, 12,see Fig. 2., A projection or thickened portion'15 of the spring 10 may be provided to serve the pin 15. v c v Theother and inner ends of the coiled springs 10 are shown secured inposition between the discs 2, 3, by means of the bolts 1 16 which serveas distance pieces between said'discs 2,3,and as means for connectin thesame. As indicated 8, may be constructed with'bosses or thick as a stopto engage the cross-pieces 11, 12, at the opposite sideto at 17, thediscs 2,,

ened at the points where the holes are formed for the reception ofthebolts 16.

As represented in Fig. 2, the bolts are dis-. circle symmetricallyaround, the

said springs. This construction does not preclude the wheel rotating inthe reverse direction when the vehicle is being moved backwards. i

and inner ends of From a consideration of the drawings it will beunderstood that the rim portion 6 move in the guideway provided betweenthe outer portions ofthe discs 2,8, against the resilient action of thesprings 10.

\Vhat Iclaim as my invention and desire to protect by Letters Patent isp A spring wheel for road vehicles, comprising a rim portion whichcarries the with the attached flanges 7, 8, is able to v tyre and isconstructed internally with twov parallel inwardly directed annularflanges, cross-p eces connecting said flanges, a hub portion, discsconnected to said hub 'portion between Which the parallel inwardly Idirected flanges Work and are guided, and

' coiled springs one end of each of which i l is attached to certain ofthe cross-pieces and V discs, theineans for attach .ing each spring tothe cross-pieces including I the other to the a set-screW, a pin passingthrough the spring and a stop provided on the spring, as set forth. 7 10In testimony whereof I name to this specification.
